Description

Technical Field

[0001] The present invention relates to the technical field of smart door locks, and in particular to an anti-interference smart door lock. Background Art

[0002] Smart door locks are improved upon traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. Although smart locks have greatly improved security compared to traditional mechanical locks, there are still many external factors that interfere with smart locks and prevent them from opening normally.

[0003] A smart door lock with a waterproof fingerprint recognition function provided in China Patent Publication No. CN115929123B relates to the technical field of smart door lock equipment. The smart door lock with a waterproof fingerprint recognition function includes a water removal mechanism. The smart door lock with a waterproof fingerprint recognition function uses two sponge boards to absorb water stains and sweat through the water removal mechanism. The fingers can squeeze the water at the bottom of the sponge board into the water outlet, which is convenient for reducing the moisture in the sponge board. Pressing down the fingers can not only squeeze out the water in the sponge board, but also start the delayed heating device, which is heated by the electric heating plate and locked in the temperature by the insulation box to evaporate the residual moisture in the sponge board and maintain the continuous water absorption capacity of the sponge board; through the delay component, the second spring is restored, and the lower pressure rod moves up accordingly. The retaining ring is blocked by the elastic bullet head and cannot move up immediately, delaying the time for the lower pressure rod to move up, increasing the heating time of the electric heating plate, and evaporating the moisture on the sponge board.

[0004] In actual use, this type of smart lock with an exposed fingerprint verification panel cannot automatically clean the residue on the fingerprint panel. When residue is retained, the user needs to wipe it with paper or cloth. If it is not cleaned in time, the residue will absorb dust in the air and dry and harden, thus affecting the next use. At the same time, this type of smart lock with an exposed fingerprint verification panel is not safe enough. Verification can be triggered as long as it is touched, and it does not have a protective structure. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0034] Example: Figure 1-10 As shown, an anti-interference smart door lock comprises a lock shell 4, a door handle 3 is rotatably mounted on the front side wall of the lock shell 4, a digital button 26 and a fingerprint panel 9 are arranged on the front side wall of the lock shell 4 above the door handle 3, a mounting groove 10 is provided on the front inner wall of the lock shell 4, the bottom of the fingerprint panel 9 is rotatably connected with the inner walls on both sides of the mounting groove 10, a protective shell 1 is provided on the front side wall of the lock shell 4 at the outer side cover of the digital button 26 and the fingerprint panel 9, the protective shell 1 and the lock shell 4 are slidably arranged, a shell driving mechanism is arranged at the connection between the protective shell 1 and the lock shell 4, and the shell driving mechanism simultaneously drives the rotation of the fingerprint panel 9, and a pressing switch for starting the shell driving mechanism is arranged at the front end of the door handle 3;

[0035] In actual use, when the smart door lock is put into use, the user presses the push switch on the door handle 3, which triggers the shell drive mechanism, causing the protective shell 1 to slide open longitudinally, thereby exposing the digital keys 26 and fingerprint panel 9 hidden behind the protective shell 1. While the protective shell 1 moves, the shell drive mechanism drives the fingerprint panel 9 to rotate and tilt, causing the fingerprint panel 9 to stay at the optimal fingerprint verification angle.

[0036] A cleaning assembly 15 is installed in the protective shell 1, and a lateral driving mechanism is provided in the cleaning assembly 15 and the protective shell 1;

[0037] The lateral driving mechanism drives the cleaning component 15 to perform a comprehensive cleaning operation on the digital keys 26 and the fingerprint panel 9;

[0038] The transverse driving mechanism includes a rectangular frame 16, a second threaded rod 17, a micro motor 29 and a second slider 18. The rectangular frame 16 is fixedly installed on the inner top of the protective shell 1. The second threaded rod 17 is rotatably installed on the inner top and bottom of the rectangular frame 16. The number of the second threaded rods 17 is two groups and they are sequentially located at the inner walls of both sides of the rectangular frame 16. The micro motor 29 is fixedly installed on the bottom of the rectangular frame 16. The output end of the micro motor 29 longitudinally penetrates the rectangular frame 16 and is fixedly connected to the second threaded rod 17. The second slider 18 is threadedly installed on the second threaded rod 17. The corresponding side wall of the second slider 18 is fixedly connected to the cleaning assembly 15.

[0039] The micro motor 29 drives the second threaded rod 17 to rotate. At this time, the second slider 18 is fixedly limited by the cleaning assembly 15, so that the second slider 18 cannot rotate with it, so that the second slider 18 can carry the cleaning assembly 15 to move longitudinally in the direction of the second threaded rod 17, so as to cooperate with the cleaning assembly 15 to clean the digital keys 26 and the fingerprint panel 9, and avoid the situation where the residue on the digital keys 26 and the fingerprint panel 9 interferes with the verification;

[0040] The cleaning assembly 15 includes a movable plate 19, a fixed plate 20, an inclined convex plate 21, a return spring 22, a guide rod 23, a brush 24, a rubber wiper 25 and an inclined groove 34. The fixed plate 20 is fixedly connected to the second slider 18. A guide rod 23 is slidably installed in the middle of the fixed plate 20. The number of guide rods 23 is three groups and they are equidistantly arranged. The guide rod 23 is located at one end of the front side of the fixed plate 20 and is fixedly installed with the inclined convex plate 21. The bottom of the inclined convex plate 21 is fixedly installed with a return spring 22, and the return spring 22 is sleeved on the guide rod 23. An inclined groove 34 matching the inclined convex plate 21 is provided on the inner top of the protective shell 1. The guide rod 23 is located at one end of the rear side of the fixed plate 20 and is fixedly installed with the movable plate 19. The rear side wall of the movable plate 19 is fixedly installed with a rubber wiper 25 and a brush 24, and the rubber wiper 25 is located above the brush 24.

[0041] When the transverse driving mechanism is driven, the inclined convex plate 21 slides out of the inclined groove 34, causing the inclined convex plate 21 to be compressed, thereby squeezing the guide rod 23 and the return spring 22, causing the movable plate 19 to carry the brush 24 and the rubber scraper 25 toward the direction of the digital keys 26 and the fingerprint panel 9 and fit with the digital keys 26 and the fingerprint panel 9. At this time, the residues on the digital keys 26 and the fingerprint panel 9 can be cleaned by cooperating with the transverse driving mechanism.

[0042] like Figure 1 As shown, the front bottom of the protective shell 1 is located at the closing part with the lock shell 4 and is provided with a plurality of groups of discharge ports 2 arranged equidistantly. The front side wall of the protective shell 1 is horizontally arranged with the front side wall of the lock shell 4 where the door handle 3 is installed. The lock shell 4 is provided with a cavity for installing a battery below the door handle 3.

[0043] When the brush 24 and the rubber scraper 25 scrape off the residue and drop it below the protective shell 1 , the residue can directly fall to the ground through the discharge port 2 .

[0044] like Figure 2 As shown, a movable cover 8 is fixedly mounted on the rear inner wall of the lock housing 4 . The movable cover 8 is arranged in an arc-shaped structure and matches the rotational motion trajectory of the fingerprint panel 9 .

[0045] After the fingerprint panel 9 is tilted, the inside and outside of the lock housing 4 will not be connected, thereby avoiding the problem of debris directly entering the lock housing 4 and causing internal damage. At the same time, the movable cover 8 can further limit the rotation angle of the fingerprint panel 9.

[0046] like Figure 2 and 7 As shown, the housing driving mechanism includes a dual-axis motor 5, a connecting plate 6, a first slide groove 7, a first slider 12, a connecting rod 13, a first threaded rod 14, a second gear 32, a third gear 33, a fixing block 31 and a connecting rod 30. The inner wall of the lock housing 4 is fixedly mounted with a connecting plate 6, and the inner walls on both sides of the lock housing 4 are provided with a first slide groove 7. The first threaded rod 14 is rotatably mounted on the top and bottom of the inner side of the first slide groove 7. The third gear 33 is fixedly mounted on the top of the first threaded rod 14. The top of the connecting plate 6 is fixedly mounted There is a dual-axis motor 5, a connecting rod 30 is fixedly installed at the output end of the dual-axis motor 5, a second gear 32 meshing with a third gear 33 is fixedly installed at the free end of the connecting rod 30, a fixing block 31 is fixedly installed on the top of the connecting plate 6, the fixing block 31 is sleeved on the connecting rod 30 and is slidably connected to the connecting rod 30, a first slide groove 7 has a first slider 12 built in, the first slider 12 is sleeved on the first threaded rod 14 and is threadedly connected to the first threaded rod 14, and the outer wall of the first slider 12 is connected to the protective shell 1.

[0047] When the user triggers the push switch, the dual-axis motor 5 drives the connecting rod 30 and the second gear 32 to rotate, and the third gear 33 and the first threaded rod 14 rotate, causing the first slider 12 in the first slide groove 7 to move longitudinally on the first threaded rod 14, thereby driving the protective shell 1 to perform longitudinal lifting movement;

[0048] like Fig. 9 and 10 As shown, the housing driving mechanism also includes a first gear 11, a mounting shell 36, a movable slot 35, a connecting rod 13, a fourth gear 39, a first movable rod 37 and a second movable rod 40. The first gear 11 is fixedly installed at the rotating shaft of the fingerprint panel 9 in the mounting slot 10, and the inner side wall of the lock housing 4 is fixedly installed with mounting shells 36 on both sides of the fingerprint panel 9. The fourth gear 39 is rotatably installed in the middle of the mounting shell 36. The front and rear side walls of the fourth gear 39 are meshed and installed with the first movable rod 37 and the second movable rod 40 in sequence. The front side of the first movable rod 37 is fixedly installed with the first movable rod 37. The wall is provided with teeth meshing with the first gear 11, the first movable rod 37 and the second movable rod 40 are both arranged in an L-shaped structure, the first movable rod 37 and the second movable rod 40 are arranged in a staggered and symmetrical manner, and an elastic buckle 38 is fixedly installed on the top of the second movable rod 40, and the opening of the elastic buckle 38 is located at the top, and the corresponding side walls of the first slider 12 are fixedly installed with connecting rods 13 in turn, and the connecting rods 13 match the elastic buckles 38, and the outer wall of the mounting shell 36 is located directly below the connecting rod 13 and is provided with a movable groove 35 for the movement of the connecting rod 13.

[0049] When the protective shell 1 is in a closed state, the connecting rod 13 is located in the elastic buckle 38, and the second movable rod 40 is at the lowest point. When the protective shell 1 is opened, the first slider 12 moves longitudinally. At this time, the connecting rod 13 carries the second movable rod 40 to move longitudinally, causing the fourth gear 39 to rotate, resulting in the first movable rod 37 to move in the opposite direction of the second movable rod 40. When the first movable rod 37 moves, the first gear 11 is engaged with the first movable rod 37, thereby causing the first gear 11 to rotate, causing the fingerprint panel 9 to rotate and tilt. When the fingerprint panel 9 rotates to the maximum angle limited by the movable cover 8, the tilting is completed. At this time, the connecting rod 13 continues to move longitudinally and disengages from the elastic buckle 38, and the opening movement of the protective shell 1 can be continued.

[0050] like Figure 4 As shown, the initial state of the fixed plate 20 and the inclined convex plate 21 is a non-contact state, the top of the inclined convex plate 21 is arranged in an arc-shaped structure, and the initial state of the brush 24 and the rubber wiper 25 is not in contact with the front side wall of the lock housing 4.

[0051] The brush 24 and the rubber wiper 25 do not interfere with the lock housing 4 when not in operation, thereby preventing fingerprints and passwords from being accidentally touched.

[0052] like Figure 2 As shown, both side walls of the protective shell 1 are threadedly installed with hexagon socket screws, the hexagon socket screws are threadedly connected to the first slider 12, and the protective shell 1 is fixedly connected to the first slider 12 through the hexagon socket screws.

[0053] The use of the hexagon socket screws ensures the detachability of the connection structure and can also avoid arbitrary disassembly to a certain extent, thereby ensuring that the brush 24 and the rubber wiper 25 can be replaced normally.

[0054] Working principle:

[0055] Before use: the protective shell 1 is in a closed state. When unlocking is required, the push switch on the door handle 3 is pressed first, so that the push switch triggers the operation of the dual-axis motor 5, thereby driving the connecting rod 30 and the second gear 32 to rotate. At this time, the third gear 33 and the first threaded rod 14 rotate, so that the first slider 12 in the first slide groove 7 is located on the first threaded rod 14 and moves longitudinally, so that the protective shell 1 is opened longitudinally. While the first slider 12 moves, the carrying connecting rod 13 can pull the second movable rod 40, so that the fourth gear 39 rotates, causing the first movable rod 37 to move in the opposite direction to the second movable rod 40. While the first movable rod 37 moves, the first gear 11 is engaged with the first movable rod 37, so that the first gear 11 rotates, thereby causing the fingerprint panel 9 to rotate and tilt. When the fingerprint panel 9 rotates to the maximum angle limited by the movable cover 8, the tilting is completed. At this time, the user can perform digital verification and password verification;

[0056] After the verification is completed, wait for the protective shell 1 to be reset. At this time, the micro motor 29 is driven to drive the second threaded rod 17 to rotate. Since the second slider 18 is fixed and limited by the cleaning component 15, the second slider 18 cannot rotate with it, so that the second slider 18 carries the fixed plate 20 to move longitudinally. At this time, the inclined convex plate 21 slides out of the inclined groove 34, causing the inclined convex plate 21 to be compressed, thereby squeezing the guide rod 23 and the reset spring 22, causing the movable plate 19 to carry the brush 24 and the rubber wiper 25 to approach the direction of the digital keys 26 and the fingerprint panel 9 and fit with the digital keys 26 and the fingerprint panel 9. At the same time, the brush 24 and the rubber wiper 25 after fitting move longitudinally to scrape off the residue on the digital keys 26 and the fingerprint panel 9 to avoid the residue on the digital keys 26 and the fingerprint panel 9 causing interference during verification.

[0057] After use, the residue on the fingerprint panel 9 is removed by the brush 24 and the rubber scraper 25, so that the fingerprint panel 9 will not be interfered with the verification of the fingerprint due to the debris remaining on the panel during the next use. At the same time, the protective shell 1 is closed to prevent external factors from directly touching the fingerprint panel 9 and interfering with the verification of the fingerprint panel 9.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
